In order to improve the convenience of users, the utility model provides a shared charger control device which is applied to a shared charger.
Referring to fig. 1, in an embodiment, the shared charger control device provided by the present invention includes:
a memory 10.
And a timer 20, wherein the timer 20 is used for starting timing when triggered and outputting a corresponding timing signal.
The communication circuit 30, the communication circuit 30 is used for being connected with the mobile device in a communication mode, and the communication circuit 30 is used for receiving a charging trigger signal sent by the mobile device.
And the input end of the charging device 40 is electrically connected with a power supply end, and the output end of the charging device 40 is electrically connected with a charging output end. And
and the control circuit 50, wherein the control circuit 50 is electrically connected with the controlled terminals of the memory 10, the timer 20, the communication circuit 30 and the charging device 40 respectively.
And the control circuit 50 is used for setting the charging time length and triggering the timer 20 to start timing according to the charging trigger signal, and outputting a corresponding remaining time signal to be stored in the memory 10.
The control circuit 50 is further configured to determine the remaining charging time period according to the remaining time signal stored in the memory 10 when the power is turned on again.
The control circuit 50 is further configured to trigger the timer 20 to start timing according to the remaining charging duration, and control the charging device 40 to maintain an operating state in the remaining charging duration according to a timing signal sent by the timer 20, so that the charging device 40 converts the voltage of the power source terminal and outputs the converted voltage to the mobile device to charge the mobile device.
The control circuit 50 is further configured to set a charging duration and trigger the timer 20 to start timing according to the charging trigger signal;
the control circuit 50 is further configured to control the charging device 40 to maintain a working state within the charging duration according to the timing signal sent by the timer 20, so that the charging device 40 performs voltage conversion on the voltage accessed by the power source end and outputs the voltage to the mobile device, so as to perform a charging operation on the mobile device.
In this embodiment, the memory 10 may adopt a nonvolatile memory, for example, an EPROM memory 10, an EEPROM memory 10, a Flash memory, and other nonvolatile memories, so that, at the moment that the shared charger is powered off, the remaining time signal stored in the memory 10 will not be lost, so that the control circuit 50 that is powered on again can determine the remaining charging time remaining in the charging time according to the remaining time signal.
In this embodiment, it should be understood that, in the use of the shared charger, a user often makes a mobile device, for example, a mobile phone and the communication circuit 30 in the shared charger realize wireless communication connection through a wireless communication network, such as WIFI, 4G/5G, a local area network, bluetooth, etc., by means of code scanning or manual decoding, and after selecting a corresponding charging duration and making a payment on a specific APP interface, a charging trigger signal is transmitted from the mobile device to the shared charger.
In this embodiment, it should be understood that the power source terminals of a common shared charger are plugs, and are plugged into a socket, and the voltage of the power source terminals is 220V ac power, so that the charging device 40 may include a rectifying device and a voltage step-up/step-down device, so as to be able to convert the 220V ac power into the charging voltage required by the mobile device. The control circuit 50 may control the start or the stop of the buck-boost device by outputting a corresponding control signal to the enable terminal of the buck-boost device, so as to control the start or the stop of the shared charger. In another embodiment, the charging device 40 may further be provided with a charging switch circuit 43, the charging switch circuit 43 is disposed between the output terminal of the buck-boost device and the charging output terminal of the shared charger, and the control circuit 50 may control the charging switch circuit 43 to enable or disable the shared charger.
In this embodiment, the timer 20 may be implemented by an external timer 20 such as a timing IC, a crystal oscillator, and the like, when the control circuit 50 receives the charging trigger signal, the control circuit 50 determines the current charging duration, and then the control circuit 50 triggers the timer 20 to start timing, and controls the charging device 40 to be in the working state in the charging duration according to the timing signal fed back by the timer 20, so that the user can access the mobile device for charging at any time in the charging duration.
In this embodiment, the control circuit 50 can be implemented by a main control chip, such as an MCU, a DSP (Digital Signal processing) chip, and an FPGA (Field Programmable Gate Array). Wherein, the main control chip is internally integrated with a computing module. As can be seen from the above embodiments, when receiving the charging trigger signal, the control circuit 50 triggers the timer 20 to start timing, and keeps the charging device 40 in the operating state for the charging duration according to the timing signal sent back by the timer 20. Meanwhile, the control circuit 50 calculates the remaining charging time within the charging time according to the timing signal through an internal calculation module, and outputs a corresponding remaining time signal to be stored in the memory 10.
If the shared charger is powered off and then powered on again at this time, the control circuit 50 determines how much remaining time remains currently according to the remaining time signal in the memory 10, and starts the timer 20 again, and controls the charging device 40 to continuously maintain the working state in the remaining time according to the timing signal sent by the timer 20, so that the user can access the mobile device to charge the mobile device at any time in the remaining charging time, and the user does not need to scan codes or manually input passwords to unlock, thereby improving the convenience of use.
Specifically, for example, when the current user purchases 1 hour of charging time by means of code scanning, the control circuit 50 determines the 1 hour of charging time according to the charging trigger signal, and then triggers the timer 20 to start timing and controls the charging device 40 to start operating, and keeps the charging device 40 in an operating state for 1 hour according to the timing signal returned by the timer 20, and at the same time, calculates the remaining charging time, and outputs a corresponding remaining time signal to the memory 10. If half an hour passes, the hotel is suddenly powered off, the shared charger is powered off, after a period of time, the hotel power is recovered, and the shared charger is powered on again, at this time, the control circuit 50 determines that the remaining charging time of half an hour still remains according to the remaining time signal in the memory 10, and controls the charging device 40 to still keep a working state within half an hour, and at this time, the user only needs to directly access the mobile device, and can continue to charge within the remaining half an hour.
The utility model sets the communication circuit 30 for communication connection with the mobile device and accesses the charging trigger signal transmitted by the mobile device, so that the control circuit 50 sets the charging duration and triggers the timer 20 to start timing according to the charging trigger signal, and outputs a corresponding remaining time signal to be stored in the memory 10, so that the control circuit 50 reads the remaining time signal in the memory 10 when being powered on again, determines the remaining charging duration according to the remaining time signal, triggers the timer 20 to start timing according to the remaining charging duration, and controls the charging device 40 to keep working in the remaining charging duration according to the timing signal sent by the timer 20, so that the charging device 40 converts the voltage accessed by the power supply end and outputs the converted voltage to the mobile device, thereby charging the mobile device. Therefore, after the shared charger is powered on again, the charging device 40 can be controlled to keep the working state in the residual charging time according to the residual charging time recorded in the memory 10 before power failure, the user does not need to scan codes again or manually input passwords for unlocking, the user can continuously access the mobile device to the shared charger and charge the mobile device in the residual charging time, and the use convenience of the user is improved.
Referring to fig. 3, in an embodiment of the present invention, the memory 10 is a Flash memory, the Flash memory is electrically connected to the control circuit 50, and the timer 20 includes a timing IC. The communication circuit 30 includes a wireless communication chip. The control circuit 50 includes a main control chip. The main control chip is respectively electrically connected with the timing IC, the wireless communication chip, the Flash memory and the controlled end of the charging device 40.
In this embodiment, the main control chip, the wireless communication chip, the timing IC and the Flash memory may be integrated in the same integrated chip. Therefore, the size of the circuit board can be reduced, and the production cost is reduced.
Referring to fig. 3, in an embodiment of the present invention, the plug is connected to the socket in a pluggable manner, and the power end is used for accessing household electricity, and the charging device 40 includes:
the input end of the rectifying circuit 41 is connected with a power supply end, and the rectifying circuit 41 is used for rectifying the household electricity connected with the power supply end and then outputting a first direct current voltage.
The input end of the DC-DC circuit 42 is electrically connected to the output end of the rectifying circuit 41, and the DC-DC circuit 42 is configured to convert the first direct-current voltage and output a second direct-current voltage.
And the input end of the charging switch circuit 43 is electrically connected with the output end of the DC-DC circuit 42, the controlled end of the charging switch circuit 43 is electrically connected with the main control chip, and the output end of the charging switch circuit 43 is electrically connected with the charging output end.
And a charging switch circuit 43 for turning on/off a path between the output terminal of the DC-DC circuit 42 and the charging output terminal under the control of the main control chip.
In this embodiment, the rectifying circuit 41 may be implemented by a rectifying bridge, and it should be understood that a conventional shared charger generally accesses a socket through a plug to obtain electricity, the socket generally provides conventional household electricity, that is, 220V ac, but the mobile device generally uses dc to charge, so that the accessed household ac needs to be converted into dc, for example, the 220V ac needs to be converted into the first dc voltage by using the rectifying bridge.
It should be understood that, in practical applications, the voltage value of the first dc voltage directly output after the rectifying circuit 41 rectifies the household electricity is high, and the charging voltage requirement of the mobile device cannot be met. For this reason, in the present embodiment, the step-down conversion of the first DC voltage to the second DC voltage, which may be a standard charging voltage of the mobile device, for example, 5V, 12V, 20V, etc., may be realized by the DC-DC circuit 42, such as a DC-DC step-down circuit. The DC-DC circuit 42 can be implemented by selecting a buck chip, and according to the specification of the buck chip, a user can set a resistance by changing the output of the peripheral circuit of the buck chip, so as to change the output value of the buck chip, thereby meeting the charging voltage requirements of different mobile devices.
In this embodiment, the charging switch circuit 43 may be implemented by a switch tube, such as an IGBT, an NMOS, or a PMOS, and may also be implemented by a relay. As can be seen from the foregoing embodiments, after the user establishes a communication connection between the mobile device and the communication circuit 30 by using the mobile device to scan a code or manually input a password for decoding, the communication circuit 30 receives a charging trigger signal transmitted from the mobile device, and the control circuit 50 sets a charging duration and triggers the timer 20 to start timing according to the charging trigger signal, and controls the charging device 40 to maintain an operating state during the charging duration, that is, during the charging duration, the charging switch conducting signal is output to control the charging switch circuit 43 to conduct a path between the output terminal of the DC-DC circuit 42 and the charging output terminal. When the control circuit 50 determines that the total on-time of the charging switch circuit 43 has reached the set charging period according to the timing signal from the timer 20, it outputs a charging switch off signal to open the path between the output terminal of the DC-DC circuit 42 and the charging output terminal. The charge switch circuit 43 may be an analog signal, for example, a high level signal is turned on and a low level signal is turned off, or a low level signal is turned on and a high level signal is turned off.
In another embodiment, referring to fig. 4, the DC-DC circuit 42 further has a second output terminal, and the second output terminal of the DC-DC circuit 42 is electrically connected to the main control chip, the wireless communication chip, the timing IC and the Flash memory, respectively.
The DC-DC circuit 42 is further configured to perform voltage conversion on the first direct-current voltage output by the rectifying circuit 41, and then output the first direct-current voltage to the power terminals of the main control chip, the wireless communication chip, the timing IC, and the Flash memory, so as to provide working voltages for the main control chip, the wireless communication chip, the timing IC, and the Flash memory.
It should be understood that, since the shared internal devices of the charger also need to maintain the power-on operating state through the household power plugged in through the plug, the shared internal devices of the charger, such as the main control chip, the wireless communication chip, the timing IC and the Flash memory in the above embodiments, often cannot bear such a large voltage.
For this reason, in this embodiment, the DC-DC circuit 42 may select a buck IC capable of outputting 2 sets of different voltages, for example, one output outputs 5V voltage for providing operating voltage for the mobile device, and the other output outputs 3.3V for providing operating voltage for the main control chip, the wireless communication chip, the timing IC and the Flash memory in the above embodiments. In addition, the shared charger control device may be directly provided with a plurality of DC-DC circuits 42, the input ends of the plurality of DC-DC circuits 42 are all connected with the output end of the rectifying circuit 41, the output ends of the plurality of DC-DC circuits 42 are respectively connected with the power ends of a plurality of devices in a one-to-one correspondence manner, for example, the working voltages of the main control chip, the wireless communication chip, the timing IC and the Flash memory in the above embodiment are different, and the plurality of DC-DC circuits 42 may convert the first DC voltage into a plurality of DC voltages with different voltage values, thereby realizing respective provision of the corresponding working voltages for the main control chip, the wireless communication chip, the timing IC and the Flash memory in the above embodiment.
Through the arrangement, the shared charger control device not only can realize the charging operation of mobile equipment such as a mobile phone, but also can be compatible with the working voltage requirements of different devices in the shared charger control device, so that the compatibility of the shared charger control device for the devices with different working voltage requirements is improved.

and the indicating device 50, wherein the indicating device 50 is electrically connected with the control circuit 50.

In this embodiment, the indicating device 50 may be implemented by a display device, such as a display screen, and the main control chip in the control circuit 50 may calculate the chargeable duration that can be used by the current shared charger according to the charging duration set in the previous embodiment and the timing signal sent by the timer 20, and control the display screen to display the current remaining chargeable duration, so that the user can more directly know the remaining time that can be used by the current shared charger for charging. Through the setting, the user can directly confirm the current residual charging time, and does not need to inquire at a mobile phone end after scanning codes through mobile equipment such as a mobile phone, so that the use convenience of the user is improved.
